I really wish FR had an "ignore poster" feature.
It's been done. I can make any posts by any number of posters disappear completely. Or make FRiends' comments more prominent. Custom scripting and stylesheets using the Firefox web browser. You can see the work I've done at my FR scripting
website. Not quite ready for a public release yet. Heh-heh, not sure if anyone is interested in a new look/feel/features for FR. I'm working on the full extension now.
